The OS X Yosemite still runs in the beta form though Apple intends to work it on MAC based on the running of OS X Mavericks on MAC. The appearance and new features can be handled later but the prerequisites for running Yosemite on MAC are –
The 2008 or later versions of the following:
- MacBook Air
- Mac Pro 9
And the mid 2007 or later versions of the following:
- MacBook Pro
And finally, the 2009 or later version of
- Mac Mini
In addition to these you will be told that you need a minimum of 2GB RAM but practically speaking, ask anybody who has done this before, you actually need a minimum of a 4GB RAM.
You also need a minimum of 8GB drive space but again, the minimum space you need is practically 16GB as you need to test the default applications and some of your favorites. Ideally, you should have 50GB to 100GB additional storage to be able to test Yosemite for the complete apps for a beta test environment.
